'function' : event_source has no events
You attempted to use event_source on a class that has no event methods. To fix this error, add one or more events to the class.
The following sample generates C3701:
[ event_source(native) ] class CEventSrc { public: // uncomment the following line to resolve this C3701 // __event void fireEvent(int i); }; // C3701 void main() { }
